I Patent July 21, 1908.

Application filed January 7, 1908. Serial No. 409,6 51.

To all 'it'may concern:

Be- 1t known that I, HENRY AUGUST Wmmnoxn, a citizen of the United States,

- anda resident of Manitowoc, in the county pt Manitowoc and State of Wisconsin, have mvented a new and improved Heating and.

Ventilating System, of which the following is ha full, clear, and exact description.

This invention relates to certain improvements in heating and ventilating systems adapted for use in school-rooms and the. like, and relates more particularly to the means for-automatically establishing the desired circulation of the air, the withdrawal of the foul air, and the supplying of fresh air.

In a system embodying my invention, the air and smoke conduits are so arranged that the foul air leaving the room adjacent the floor, is heated by the heat of the gaseous products of combustion, so as to establish an upward current of the foul air, and one object ofthe invention is to utilize a portion of whereby said foul air is heated.

the space intermediate the walls as a portion of the foulalr conduit, and to provide a drum within the room adjacent'the' ceilin con-' nectmg with SfllCl space within the wa sand surrounding a portion of the smoke In the preferred arrangement for employing my s stem, a stove is provided having an air con uit-in conjunction therewith, the

outlet from said air conduit delivering to the room, and the inlet to said conduit having damper-controlled branches, one of which takes in air from'adjacent the floor and the otherof which may take inair from the outside of the building. The smoke or gaseous prroducts of combustion from the stove pass om the stove througha stove-pipe entering the chimney adjacent the ceiling, and a hori- 'zontal portion of this stove pipe is surrounded it of a room having an apparatus designed for.

bya drum forming a portion of the air conduit for the escape of the foul air, another portion of this foul air conduit being adjacent the floor. I 7

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference lndicate corresponding parts in all the figures,

and in which Figure 1 is a perspective view 'ofa portion carrying out my improved s stem; Fig. 2 is a transverse section through t e wall, chimney niid drum; Fig. 3 is a vertical section on the linel3-f3 of Fig. 2g'a nd Fig. 4 is a side elevastove laterall tion' of the stoveand the fresh air conduit, a portion thereof being shown in section.-

My improved system is especially designed for use in connection with school-rooms, halls, and the like, heated by stoves, although it ;may be employed wherever a heating of the air and an automatic circulation thereof'is desired. The special stove 10,

which I have illustrated for facilitating the heating and circulating of the fresh air, is provided with an air chamber ll at the rear side thereof, having an inlet conduit provided with two damper-controlled branches 12 and 13. ,The branch 12 extends through the wall 14 of the building to the outside thereof, and

:the branch 13 terminates adjacent the floor.

- 15, or the colder air adjacent the floor may be taken in through the branch 13 to the air chamber 11 and discharged into the room through the conduit 15. In other words, an automatic circulation'of the air is established by the upward movement of the heated air within the air chamber and the conduit 15. The dampers in the branches 12 and 13 may be adjusted to take in the air from the desired source.

The wall or (partition 17 of the room is preferably forme of vertically-disposed studding 18, havinglath and plaster, or other suitable covering upon opposite sides thereof, whereby the s ace intermediate the sides forms verticallyisposed conduits, and one of these conduits is preferably employed as 'a portion of the outlet conduit for the foul air. As shown, the space between two of the studs forms a conduit-19, at the lower end of which is a foul air inlet 20, covered by a reticulated metal plate to prevent the entrance of large foreign bodies. A suitable brick chimney is provided, preferably, subdlv ded into two conduits orpassages, one conduit or a'ssage 21 for the gaseous products of com-- ustion and the other passage 22 for the foul air. The stove-pipe 16 extends upwardly ed by an elbow 24 at one end to the conduit.

19 and connected'by an elbow 25 atthe opposite end to the conduit or passage 22 in the chimney. The chimney conduit or passage 22 also communicates at its lower end with the interior of the room by an air inlet 26,

normally covered by a reticulated metal plate. The foul and colder air adjacent the floor may enter both the inlets 20 and 26, and that entering the inlet 20 pass upward within the wall of the room to the elbow 24, then through the drum 23 and elbow 25 to the chimney passage 2-2. .The air .within the drum becomes heated from the heat of the smoke in the stove-pipe l6, and as the upper outlet end of the passage 22 is open to the atmosphere and this passage is larger than the conduit 19 within the walls, an upward circulationof air is established through the conduit 19 and drum 23 to the passage 22. By means of this arrangement, all parts of the foul air conduit save the drum 23 and its connections, are concealed from view, and the drum is adjacent the ceiling, Where it does not interfere with the free use of the -room. The stove-pipe passesdirectly from the stove to the chimney and does not engage esaeei with the wall at any part, save where it passes through into the chimney; thus the liability of setting fire to the building from the heated pipe is avoided, and the air which rooms, the combination of a foul air escape conduit, including a'drum ad acent 'the'celling of the room, two vertically-disposed passages within the walls of the room; one of said passages communicating with one end of the drum and'with the room adjacent the floonthereof, and the other of'said passages communicating with the opposite end of said drum and With the outside atmosphere, the last-mentioned passage being formed of noncombustible material, a stove within said room, anda stove-pipe extending therefrom and through said drum.

, In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
